Locked up with deep-breathing krill

Krill and shrimp: netted in the interests of science.

This morning started with a kind of international incident. My fellow Brit Carl Ballantyne and I were horrified to see our expedition leader Stig put sugar on his black pudding at breakfast. These trips are, of course, very international. With scientists from Norway, Russia, Poland, the UK, Germany and other countries on board, there is plenty of scope for “intercultural exchange”, although I still prefer my black pudding straight and spicy.

In between times, I found myself earning my passage on the Helmer Hanssen, working briefly – believe it or not – in the fridge with a load of krill! As the scientists work in shifts through the night and sleep when they get a chance, Carl was having trouble finding an assistant to help him note down his hourly measurements. He is monitoring the respiration of krill samples. So I found myself putting on a head torch and going into the dark fridge with a list and a pencil.

Carl is checking the respiration of certain species, mainly krill. They are living in little bottles of sea water. He puts a tube in to measure how much oxygen they are consuming, the figure appears on the computer and gets entered by hand in a notebook. That was my job. So what is this all about, I wanted to know. Again, it is all about finding out what creatures are up to in the water during these dark winter months. In summer, there is lots of respiration, Carl tells me, compared to winter. It has generally been assumed that since it’s colder and darker and there is not much phytoplankton for them to eat, they will not be feeding and so not using up much energy, which shows in the respiration. But now scientists have found that even at this time of year they are migrating vertically, that is moving up and down in the water column, so they must be using energy. Carl and co. want to find out more. Again, this is an area where not much research has been carried out in winter until fairly recently. These people really have the chance to find out things nobody knew before. Fascinating. And the iceblogger had the chance to make a tiny contribution!

Snow delays? In Norway?

De-icing monster on the approach, departure looking more likely!

De-icing monster on the approach, departure looking more likely!

Norway is one place that generally has no problem with a bit of snow, but my flight from Oslo to Longyearben on Svalbard is indeed delayed because of snow. There seems to be a queue at the de-icing stand. I am hoping there will be no problems catching the next little plane up to Ny Alesund. But as it is a fairly special flight, I am hoping the pilot and my Polar Night colleagues already in Longyearben will wait for me.

As I struggled to get out of bed early on a cold, snowy morning, I imagined what it must be like to live in the High Arctic and have a few months without any light at all. Tough going! But there is also something absolutely beautiful about snow in moonlight and starlight.

I am looking forward to seeing Ny Alesund again, although I know it will be very different in the dark. In summer, of course, it is light all year round. The weather seems to be fairly changeable. A colleague in Tromso (where I shall be heading after the scientific boat expedition) tells me there are some areas with no snow cover and others close by covered by snow drifts. “Pack for everything”, he said, and be prepared for a VERY cold spell on the horizon.

A fellow passenger told me he had been evacuated from a ship at Trondheim, because of gale force winds, force 12. So I am wondering what conditions will be like for our ship, the RV Helmer Hanssen, when it leaves Ny Alesund later today.

Meanwhile, when I left Germany yesterday, I saw hazel bushes in bloom. I reminded myself this is January. But of course it comes after the warmest year on record. The climate is changing – and I am headed for the region most affected on the whole planet, warming at around twice the average speed. I’ll keep you posted.

Arctic Ocean: “Mare incognitum”

Ny Alesund, Spitsbergen hosts the world's northernmost marine lab. (Quaile, 2007)

Ny Alesund, Spitsbergen hosts the world’s northernmost marine lab. (Quaile, 2007)

As I continue to prepare for my trip to Svalbard and the Arctic waters around the archipelago, into the Polar Night, the title of a website strikes me as particularly appropriate: Mare Incognitum  is the umbrella title for a group of Arctic research projects, including the one I will be joining this weekend at the harbour of the Arctic research base at Ny Alesund, Spitsbergen. The title was chosen to reflect the group’s view of the Arctic as “one of the least known marine ecosystems of the planet”.
